I think it's safe to say that we're still feeling the impact of the work done by Martin Luther King, Jr and his supporters. If you've never seen the "I Have A Dream" speech - please take a few minutes to watch the shortened version and, if you can squeeze in the time, please watch the full version.

I think it's important to recognize why you get National Holidays with just a tiny bit of effort. So watch those videos, read the mans Wikipedia entry and maybe reflect on some social injustices that you're glad to have seen gone by the wayside during your lifetime - always remembering that we still have a ways to go.
